學位論文簡介

The millimeter wave communication at W-band (75–110 GHz) is one of the promising approaches to provide abundant spectrum source for the wired and wireless applications with the aid of the enormous bandwidth of the fiber. Optical fiber is the ideal medium for the mm-wave transmission due to its low loss, low cost and wide bandwidth. The resultant technology is called mm-wave RoF. In this technology, the generation of optical mm-wave carrier is one of the most relevant tasks, especially for the W-band frequencies. Various techniques have been developed for generating the mm-wave carriers and transport wideband data though RoF.

The mm-wave radio-over-fiber (mm-wave RoF) can provide efficient transmission of very high data rate from the CS to the BS enabling centralized control and monitoring. Unfortunately, due to some constraints such as crossing highways or accidental regions, fiber deployment becomes expensive and impracticable. In that case, free space optical (FSO) can be an ideal alternative to supply the equivalent capacity and quality of the fiber. FSO is a wireless line-of-sight (LOS) technology that uses invisible beams of light to provide optical bandwidth connections. Severe atmospheric attenuation such as rain can de-grade the performance of the FSO link. OFDM is a high spectrally efficient modulation technique that can resist to strong turbulence and achieve very high-speed transmission as the data is distributed over a large number of orthogonal sub-carriers. OFDM-FSO system is currently being positioned as a possible 5G backhaul and fronthaul solution because it can deliver huge volumes of data at super-fast speeds, without wires.
